capture, output compare, PWM or one pulse mode output. This gives up to 12 input
captures / output compares / PWMs on the largest packages.
The general-purpose timers can work together via the Timer Link feature for synchronization
or event chaining. Their counter can be frozen in debug mode. Any of the general-purpose
timers can be used to generate PWM outputs. They all have independent DMA request
generation.
These timers are capable of handling quadrature (incremental) encoder signals and the
digital outputs from 1 to 3 hall-effect sensors.
I
Up to two I²C bus interfaces can operate in multimaster and slave modes. They can support
standard and fast modes.
They support dual slave addressing (7-bit only) and both 7/10-bit addressing in master
mode. A hardware CRC generation/verification is embedded.
They can be served by DMA and they support SM Bus 2.0/PM Bus.
Universal synchronous/asynchronous receiver transmitter (USART)
The available USART interfaces communicate at up to 2.25 Mbit/s. They provide hardware
management of the CTS and RTS signals, support IrDA SIR ENDEC, are ISO 7816
compliant and have LIN Master/Slave capability.
The USART interfaces can be served by the DMA controller.
Serial peripheral interface (SPI)
Up to two SPIs are able to communicate up to 18 Mbit/s in slave and master modes in full-
duplex and simplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes.
Both SPIs can be served by the DMA controller.
GPIOs (general-purpose inputs/outputs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current-
capable except for analog inputs.
The I/Os alternate function configuration can be locked if needed following a specific
sequence in order to avoid spurious writing to the I/Os registers.
ADC (analog to digital converter)
The 12-bit analog to digital converter has up to 16 external channels and performs
conversions in single-shot or scan modes. In scan mode, automatic conversion is performed
on a selected group of analog inputs.
The ADC can be served by the DMA controller.
